I am getting below error in my DC.
The Knowledge Consistency Checker (KCC) has detected that successive attempts to replicate with the following directory service has consistently failed.
Period of time (minutes):
The Connection object for this directory service will be ignored, and a new temporary connection will be established to ensure that replication continues. Once replication with this directory service resumes, the temporary connection will be removed.
8451 The replication operation encountered a database error.
I see in AD SITES AND SERVICES Under connection it has all connections so how should I repair and what should I do
